Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] like Figures 1-3 As shown, this embodiment provides a microwave surgical scalpel with both suction and drainage functions, comprising:

[0029] The scalpel body and the refrigerant pipe assembly are as follows: The scalpel body includes a scalpel shaft 1-4, a microwave scalpel head 1-1, and a drain pipe 1-9. The microwave scalpel head 1-1 is located at the end of the scalpel shaft 1-4, and the drain pipe 1-9 is located inside the scalpel shaft 1-4 and passes through the microwave scalpel head 1-1. The refrigerant pipe assembly includes a refrigerant pipe body 2-7 and a main unit peristaltic pump 2-6. The main unit peristaltic pump 2-6 is installed on the refrigerant pipe body 2-7 and can be switched between forward and reverse rotation. One end of the refrigerant pipe body 2-7 is connected to the drain pipe 1-9.

[0030] The working principle and beneficial effects of this utility model are as follows:

[0031] This embodiment provides a microwave surgical scalpel with both suction and drainage functions. The scalpel cauterizes the tissue around the incision to stop bleeding. A suction and drainage pipe 1-9 is installed inside the scalpel handle 1-4. The main unit's peristaltic pump 2-6 provides power for the suction and drainage process by rotating forward and backward. When the main unit's peristaltic pump 2-6 is activated in the forward direction, positive pressure is generated in the refrigerant pipe 2-7, which pumps clean water in to rinse the tissue. When the main unit's peristaltic pump 2-6 is activated in the reverse direction, negative pressure is generated in the refrigerant pipe 2-7, which draws out the bloody water after rinsing through the suction and drainage pipe 1-9, thereby providing a clear field of vision for the surgery.

[0032] Through the above structural design, drainage pipes 1-9 are set inside the microwave scalpel. By rotating the peristaltic pump 2-6 of the main unit, positive pressure flushing of clean water and negative pressure suction of blood are achieved, which can quickly deal with bleeding sites, provide a clear field of vision for surgery, and improve the accuracy and safety of the surgical procedure.

[0033] In one embodiment, the scalpel body further includes a handle assembly 1-8, a drain pipe 1-9 installed inside the handle assembly 1-8, one end of the drain pipe 1-9 connected to the refrigerant pipe assembly extending out of the handle assembly 1-8, and a scalpel shaft 1-4 installed at the end of the handle assembly 1-8.

[0034] The working principle and beneficial effects of the above scheme are as follows:

[0035] Handle assembly 1-8 is used to fix components such as the scalpel bar 1-4 and the drainage tube 1-9. During the operation, medical staff hold the handle assembly 1-8 to operate. The handle assembly 1-8 adopts an ergonomic design for easy gripping.

[0036] In one embodiment, a capillary tube 1-3 is connected to the drain pipe 1-9, and the capillary tube 1-3 is disposed inside the scalpel rod 1-4 and passes through the microwave surgical scalpel head 1-1.

[0037] The working principle and beneficial effects of the above scheme are as follows:

[0038] A capillary tube 1-3 is connected to the drainage pipe 1-9. The diameter of the capillary tube 1-3 ranges from 0.5 to 0.7 mm. The small size of the capillary tube 1-3 allows it to be installed on the microwave scalpel head 1-1 to drain water from small bleeding areas.

[0039] In one embodiment, a coaxial cable 1-2 is provided inside the tool holder 1-4, and the coaxial cable 1-2 passes through the handle assembly 1-8 and is connected to the microwave output cable connector 1-13 at its end.

[0041] The inner conductor of coaxial cable 1-2 is inserted into the tail end of the inner conductor of microwave scalpel head 1-1, connecting the inner conductor of coaxial cable 1-2 to the inner conductor of microwave scalpel head 1-1. The outer side of the inner conductor of coaxial cable 1-2 is covered with PTFE, and the outer side of the PTFE is covered with copper sheath. Microwave output cable connector 1-13 is connected to the microwave solid-state source via cable. Microwaves are conducted through coaxial cable 1-2 to microwave scalpel head 1-1 to treat the lesion and cauterize the tissue around the incision for hemostasis.

[0042] The microwave output cable connectors 1-13 use a rotating snap-fit ​​BNC connector, which is not only easy to operate but also effectively prevents external electromagnetic interference, ensuring stable signal transmission.

[0043] In one embodiment, the handle assembly 1-8 further includes a control board 1-7, a start / stop switch 1-6, a connecting cable 1-10, and an instrument cable connector 1-12. The control board 1-7 is disposed inside the handle assembly 1-8; the start / stop switch 1-6 is disposed on the outer wall of the handle assembly 1-8 and is electrically connected to the control board 1-7; one end of the connecting cable 1-10 is connected to the control board 1-7, and the other end extends out of the handle assembly 1-8 and is connected to the instrument cable connector 1-12.

[0044] The working principle and beneficial effects of the above scheme are as follows:

[0045] The control board 1-7 is connected to the main control board of the microwave ablation equipment via the instrument cable connector 1-12. The main control board inside the microwave ablation equipment (microwave ablation instrument, etc.) is connected to the microwave solid-state source. A start / stop switch 1-6 is set on the handle assembly 1-8, which can replace the foot switch on the microwave ablation equipment to control the start and stop of the microwave, increasing the flexibility of operation.

[0046] In one embodiment, a temperature measuring chip 1-5 is provided at one end of the handle assembly 1-8 and the tool holder 1-4, and the temperature measuring chip 1-5 is electrically connected to the control board 1-7.

[0047] The working principle and beneficial effects of the above scheme are as follows:

[0048] A temperature sensing chip 1-5 is installed inside the handle assembly 1-8 to monitor the temperature at the connection between the handle assembly 1-8 and the blade 1-4, preventing local overheating and burns, and guiding the start and stop of the microwave. The temperature sensing chip 1-5 also has a data storage function, which can store the scalpel model and upload it to the microwave ablation device host to achieve model matching, greatly improving the safety of operation and output.

[0049] In one embodiment, the drain pipe 1-9 is connected to a first Luer adapter 1-11, and the refrigerant pipe body 2-7 is connected to a second Luer adapter 2-8. The first Luer adapter 1-11 and the second Luer adapter 2-8 are connected.

[0050] The working principle and beneficial effects of the above scheme are as follows:

[0051] Luer adapters, also known as Luer connectors, are configured as male Luer connectors and matching female Luer connectors, respectively. The first Luer adapter 1-11 and the second Luer adapter 2-8 are configured as male Luer connectors and matching female Luer connectors.

[0052] In one embodiment, the other end of the refrigerant pipe body 2-7 is connected to a tee connector 2-5. The other two ports of the tee connector 2-5 are connected to the cleaning water bag 2-1 through the first pipe 2-9 and to the water storage bag 2-2 through the second pipe 2-10.

[0053] A first one-way check valve 2-3 is installed on the first pipeline 2-9. The fluid in the first one-way check valve 2-3 flows from the cleaning water bag 2-1 to the tee connector 2-5.

[0054] A second one-way check valve 2-4 is installed on the second pipeline 2-10. The fluid in the second one-way check valve 2-4 flows from the three-way connector 2-5 to the water storage bag 2-2.

[0055] The working principle and beneficial effects of the above scheme are as follows:

[0056] The refrigerant pipe body 2-7 is connected to the cleaning water bag 2-1 and the water storage bag 2-2 via a T-connector 2-5, eliminating the need to replace the water bags during the pumping and draining process, making operation convenient. The main peristaltic pump 2-6 is electrically connected to the main control board of the microwave ablation equipment, facilitating the control of the main peristaltic pump 2-6 to achieve the pumping and draining operation.

[0057] During negative pressure drainage, the first one-way check valve 2-3 on the first pipeline 2-9 can prevent blood from flowing into the clean water bag 2-1; after drainage stops, the second one-way check valve 2-4 on the second pipeline 2-10 can prevent blood from flowing back from the water storage bag 2-2 into the refrigerant pipe body 2-7.

[0058] like Figure 4As shown, in one embodiment, a buffer assembly is provided on the second pipeline 2-10, the buffer assembly including:

[0059] Buffer pipe 2-11 is connected to the second pipe 2-10 and is located between the second one-way check valve 2-4 and the tee joint 2-5. Buffer pipe 2-11 is inclined and the pipe opening faces the tee joint 2-5. A flange 2-12 is provided at the end of buffer pipe 2-11.

[0060] The filter cylinder 2-13 is installed inside the buffer tube 2-11. The inner end of the filter cylinder 2-13 intercepts the second pipeline 2-10. Multiple filter holes 2-14 are provided on the wall of the filter cylinder 2-13. An end plate 2-15 is provided at the end of the filter cylinder 2-13, and the end plate 2-15 is snapped onto the flange 2-12.

[0061] The working principle and beneficial effects of the above scheme are as follows:

[0062] During the blood drainage process, the blood may mix with wound tissue, easily causing blockages in the drainage system. A buffer assembly is installed on the second pipe 2-10. During use, the blood flows through the second pipe 2-10, and upon passing through the buffer pipe 2-11 area, it enters through the opening of the filter cylinder 2-13. After being filtered through the filter holes 2-14 on the wall of the filter cylinder 2-13, it enters the second pipe 2-10 on the other side of the buffer pipe 2-11. The filtered tissue is collected in the filter cylinder 2-13 and falls to its bottom. When a certain amount of filtered material accumulates, the filter cylinder 2-13 can be removed and replaced. This ensures the second pipe 2-10 remains unobstructed throughout the surgical procedure, solving the problem of frequent drainage pipe replacements due to blockages caused by blood and tissue, and reducing the difficulty of the operation. The edge of the end plate 2-15 is made of elastic material, allowing for a tight engagement or separation from the flange 2-12.
